        Remove use of static C++ objects that are destroyed at exit time (destructors)

        Create DEFINE_STATIC_LOCAL macro. Change static local objects to leak to avoid 
        exit-time destructor. Update code that was changed to fix this issue that ran 
        into a gcc bug (<rdar://problem/6354696> Codegen issue with C++ static reference 
        in gcc build 5465). Also typdefs for template types needed to be added in some 
        cases so the type could make it through the macro successfully.

        Basically code of the form:
        static T m;
        becomes:
        DEFINE_STATIC_LOCAL(T, m, ());

        Also any code of the form:
        static T& m = *new T;
        also becomes:
        DEFINE_STATIC_LOCAL(T, m, ());
